Olympic missiles 'will leave nothing to chance'

The government has confirmed that it will use ground-based air defence systems as security during the Olympic Games.

Based at six sites around London, the missiles will "provide both reassurance and a powerful deterrent" to ensure the safety of those attending the games, the Ministry of Defence (MoD) said.

"Whilst there is no reported threat to the London Olympics, the public expects that we put in place a range of measures aimed at ensuring the safety and security of this once-in-a-generation event," defence secretary Philip Hammond said.
